Differences between three types of hospital
| Variables | Pediatric hospital | Maternal hospital | General hospital | P |
|---|---|---|---|---|
| Cases, n (%) | 129 (50.0) | 82 (31.8) | 47 (18.2) | |
| Surviving ELBW infants, n (%) | 80 (62.0) | 29 (35.4) | 20 (42.6) | 0.000* |
| Died by 24 h, n (%) | 11 (8.5) | 35 (42.7) | 6 (12.8) | 0.000* |
| Mean BW (g) | 876 | 862 | 857 | 0.384 |
| Mean gestational week (weeks) | 28 | 27 | 28 | 0.642 |
| IVH, n (%) | 24 (23.3) | 21 (56.8) | 15 (39.5) | 0.001* |
| IVH III–IV, n (%) | 13 (12.6) | 2 (5.4) | 8 (21.1) | 0.129 |
| PVL, n (%) | 3 (2.9) | 4 (10.8) | 5 (13.2) | 0.053 |
| ROP, n (%) | 38 (44.7) | 13 (40.6) | 7 (30.4) | 0.465 |
| NEC, n (%) | 9 (7.6) | 1 (2.1) | 2 (4.9) | 0.380 |
| BPD, n (%) | 36 (42.9) | 14 (48.3) | 14 (66.7) | 0.148 |
| Hospital acquired infection, n (%) | 23 (19.5) | 15 (31.9) | 7 (17.1) | 0.156 |
*P values showed that survival rate and mortality was different between these three types of hospitals, and the incidence of IVH was higher in the maternal hospital. ELBW: Extremely low birth weight; BW: Birth weight; IVH: Intraventricular hemorrhage; PVL: Periventricular leukomalacia; ROP: Retinopathy of prematurity; NEC: Necrotizing enterocolitis; BPD: Bronchopulmonary dysplasia.
